When comparing Nexus 5X vs Sony Xperia X Performance, the Slant community recommends Nexus 5X for most people. In the question“What are the best Android phones?”Nexus 5X is ranked 13th while Sony Xperia X Performance is ranked 23rd. The most important reason people chose Nexus 5X is:

Stock Android offers a more streamlined experience than most other phones. While it lacks some fancy features, it doesn't come with any pre-installed bloatware, and it will receive updates almost instantly when they become available.

Pros

Pro

Clean software with quick updates

Stock Android offers a more streamlined experience than most other phones. While it lacks some fancy features, it doesn't come with any pre-installed bloatware, and it will receive updates almost instantly when they become available.

Pro

Future-ready charger

USB Type C is a new port which is reversible - you can plug it in either way. The connector is also stronger, so you shouldn't need to replace cables as frequently. It's also a brand new standard, so it isn't going to be replaced within the life of the phone.

Pro

Acceptable battery life

The battery isn't enormous at 2700mAh, but it should last a full day on all but the longest, most heavy-use days.

A looped 90 minute video at 100% brightness drained the battery by 32% which is a poor result. If the screen is on constantly, battery will drain fairly quick. In standby, the Nexus 5X barely uses any power. While most other phones will use up 10% throughout the day in idle mode, the Nexus 5X will use significantly less power thanks the the Doze feature which puts the phone into a deeper sleep.

GSMarena rates the 5X at 60h, which is enough to last a full day with regular usage.

Pro

Pretty good camera

While it won't be winning any awards, the camera takes some decent shots. Lowlight performance is acceptable, and it's pretty quick to focus and take pictures. Macro shots performed very well.

Pro

Good fingerprint scanner

The fingerprint scanner is very quick and reliable. The positioning on the back of the phone means that you won't have to change your grip (it's where your index finger naturally rests).

Pro

Works well in one hand

Being that the device has a 5.2-inch display it is quite easy to reach all corners of the screen without compromising ones grip on the device.

Pro

High end specs

Although full reviews aren't out yet (and won't be for some time), on paper the Xperia X Performance packs a lot for it's somewhat compact design. A 23MP camera, Snapdragon 820 processor, 3GB of RAM, 1080p display, and two front facing stereo speakers...looks like a powerful overall package.

Pro

Great UI

Traditionally, Sony keeps design elements familiar to stock Android, and it really looks good. They do add their own features - mini apps (which replicate dual-window functionality), as well as different battery saving modes for different levels of urgency to save power. Based on early hands on impressions, it looks like the Xperia X Performance follows with the ideology originally created with the Xperia Z lineup.

Cons

Con

Performance isn't reliable

For a mid-range phone, the Nexus 5X has decent performance, but it's far from the best. The Snapdragon 808 processor is paired with only 2GB of RAM, and for unknown reasons can become unresponsive for seconds at a time.

Con

Sub-par camera app

The default camera app doesn't do the camera any justice. The only settings you have access to are resolution, HDR, flash, and timer. There is no manual focus, white balance, ISO etc.

Sometimes the app hangs up for a few seconds and turns unresponsive.

Con

Limited storage

There is no SD card slot, and the largest storage option available is 32GB. If you like keeping lots of music/pictures/videos stored on your phone, you may want to look elsewhere

Con

Cheaply made

Compared to the more premium phones (like the Nexus 6P), the 5X components aren't as good resulting in performance issues. It's still a good phone relative to it's price though.

Con

No wireless charging

A feature implemented in the Nexus 4 and now absent in the latest Nexus devices. Those that have wireless chargers will not be able to use them with this phone.

Con

Poor multitasking performance

With only 2GB of ram the device may run into issues with mutitasking. This means screen redraws and apps that have to refresh when navigating back to them, instead of staying loaded in RAM which would be possible if there were more RAM.

Con

Uses a new cable standard

Having USB-C does allow the device to be future proof but also means that all existing USB cables will not work with it. All the micro USB chargers and cables users have built up a collection of over the years are deemed useless with this device.

Con

Uninspiring

The Sony Xperia X Performance doesn't offer much over the competition - it has actually taken a step back by removing waterproofing and using a smaller battery. The design is unique, but dated. Sony hasn't had a major design since 2012.

Con

Not available yet

Sony hasn't given a date when you can actually buy the X Performance, but sources say to expect early in the summer. It's a ways away, but it has been officially launched
